When nearly 90 percent of the batch of House ratings changes are in your favor, it’s normally great news. But with a limited House playing field, Democrats need to win virtually all of the competitive seats, and some initial takeover targets look like they are slipping out of reach.

The Congressional Leadership Fund, a super PAC backed by House Republican leadership, is pouring another $10.7 million into House races as the GOP seeks to defend their hold on the lower chamber and flip several Democratic-held seats.

The additional spending brings the fund's general election expenditures this cycle to $20.7 million in 15 House districts, nearly twice what it spent in 2014 and 2012. The super PAC spent $11.6 million in 2014 and $10.7 million in 2012.

Millennials have a reputation for being lazy, but a bipartisan crop of young congressional candidates is raising hundreds of thousands of dollars, which they’ll need, considering they are taking on the political establishment.

Considering the average age of a House member is 57, both parties could use some fresher faces to promote to voters.
